2h ail whom it may concern Be it known that I, GEO GE EvANs, of the of Toronto, Province of Ontario, .ada, have invented certain new and use;

T movements in Detachable Heels, of

is following is a specification. is invention relates to detachable rubc r cells of the type disclosed in Canadian liatent No. 1:) #28", dated October 4th, 1910, 1 which i interested, and my ob'ect is to devise hing means which will not only be cheaper to make but whioh'will per slit of thc use of less flexible, and thereforev cheaper, material in the heel itself.

5 my device requiring that the heel be to spring it over the lips of the attach m somber necessitates the use of a high grade-rubber in the heel. I therefore protoward the rear of the upper side of the heel. sremovable screw orpin serves to hold the forward part of the heel in place.

' Figure l. is a perspective section of a rubattaching 3late.constructed in my invention. Fig. 2 is her heel and. *ttCCQIdHllCeward and ofthe heel. Fig. 6 is a lan partly 1 section of a heel and attacung plate showing a modification of the 11p on the i the drawings like letters of reference indicate corresponding parts in the different figures. 4

A is .an attaching plate preferably stamped from sheet metaland adapted to be secured host or shoe. This plate is bent downwardly at itsrear end and a rearwardly extending lip 33 is formed thereon, preferably arcshaped as shown. The heel C has a socket l), formed in its upper surface andat the rearwaifd side of this socket is formed a receol is formed with a countersink F adapted to receive the forward end of the attaching plate A. as shown. As the attaching plate sa ages the heel at one end only of the sodlzet other means must be provided for holding the forward portion of the heel in place. I provide for this purpose a screw G, or its equivalent. This screw is preferably screwed up from'below through the heel and into or through the attaching plate A, as shown in Fig. 1. A hole H is preferably molded in the heel, which hole normally does not extend quite through the bottom of the heel, as shown in Fig. 2, but which is easily broken through when it is desired to hold a heel in place.

In order to securely and closely hold the heel in place through the engagement of the lip B in the recess E, l find it preferable to embed the transverse stiffener I in the heel just above the recess E as shown. As the forward part of the heel is connected with the attaching plate and therefore with the shoe at one point only, I find it desirable to also embed a stitlener J in the forward part of the heel with which stiffener the screw G preferably engages, as shown in Fig. l.

As for some purposes itmay be objectionable to have the screw pass up from below, I prefer to so arrange the heel that it may be used with an attaching plate such as shown in Figs. 3 and 4. This attaching plate, it may be seen, is provided with a downwardly bent lug K. The forward part of the heel is further provided with the. slot Lextending part way down through the heel and through the stiiiener J as indicated par= ticularly in Fig. 5. The hole M is preferably molded in the heel, as shown in Figs. 2 and 3, extending through the forward side thereof just below the stifiencr J .lhe screw G enters the hole M and screws into the lug K just below the stifl'ener so that the heel will'be held closely up against the shoa to which it is connected.

In all the forms described it will be seep that the same underlying'principle is ad hered to, namely, the formation ofthe and the plate so that a lip Ono-the latter engages a recess on the former, while a separate detachable fastener is used to secure the other end of the heel to the attaching plate or shoe. To give greater resiliency in the heel a tapered coil spring P may be inserted between the bottom of the socket and the underside of the at-taching'plate, as shown in Fig: 3.

To prevent upward bending of the rubber over the recess E, I may usetwo recesses as shown in Fig. 6 separated by a portion of rubber a which makest-ne heel practically solid at that point so that no upward bulge can occur. The plate A is of course provided with two lips B.

The great advantages of the constructions described are that the attaching plate may be cheaply formed by stamping, and as no bending of the heel is required in securing it in position a very cheap rubber may be employed if desired.

v hat I claim as my invention is z 1. An elastic heel molded to form a socket in its upper side with a recess at one end of the socket extending substantially parallel to said side in combination with a plate I adapted for connection to a shoe and having a lip formed thereon adapted to releasably engage in the recess; and a separate detachable tastening at the other end of the heel adapted to secure it to the shoe.

2. An elastic heel molded. to form a socket in its upper side with a recess at one'end of the socket extending substantially parallel to said side in combination with a plate adapted for connection to a shoe and having a lip formed thereon adapted to releasably engage in the recess; separate detachable fastening at the other end of the heel adapted to secure it to the shoe; and a transverse stifi'ener embedded in the heel adjacent said fastening.

3. An elastic heel molded to form a socket in its upper side with a recess at one end of the socket extending substantially parallel to said side in combination with a plate adapted for connection to a shoe and having a lip formed thereon adapted to relcasably engage in the recess; a separate detachable fastening at the other end of theheel securing the heel to the plate at. one point; and a transverse stiffener embedded in. the heel adjacent said fastening.

t. An elastic heel molded toform a socket in its upper side with a recess at one end of the socket extending substantially parallel to said side in combination with a plate adapted for connection to a shoe and having a. lip formed thereon adapted to releasably engage in. the recess; a separate detachable fastening at the other end of the heel adapted to secure it to the shoe; and a transverse stiffener embedded in the heel adjacent said fastening and engaged thereby.

5. An elastic heel molded to form a socket in its upper side with a recess at one end of the socket extending substantially parallel to said side in combination with a plate adapted for connection to a shoe and having a lip formed thereon adapted to releasably engage in the recess; a separate detachable fastening at the other end of the heel securing the heel to the plate at one point; and a transverse stiffener embedded in the heel adjacent said fastening, and engaged thereby.

6. An elastic heel molded to form a socket in its upper side with a recess at one end of the socket extending substantially parallel to said side in combination with a plate adapted for connection to a shoe and having a lip formed thereon adapted to releasably engage in the recess; a transverse stiffener embedded in the heel opposite to and remote from the recess; and a screw passing through said stiffener adapted to screw into the shoe.

7. An elastic hcel molded to-t'o'rm a socket in its upper side with a recess at one end oi the socket extending substantially parallel to said side in combination with a plate adapted for connection to a shoe and having a lip formed thereon adapted to releasably engage in therecess; a transverse stiffener embedded in-the heel opposite to and remote from the recess; and a screw passing through said stiffener and plate.

8. An elastic heel molded to form a socket in its upper side with two recesses side by side at one end of the socket extending sub stantially parallel to said side in combination with a plate adapted for connection to a shoe and having lips formed thereon adapted to releasably engage in the recesses; and a separate detachable fastening at the other end of the heel adapted to secure itto the shoe. 4
